Hi I am looking for data about a couple of tubes I got in my tubebox.

on the box it´s typed:

Luma Industria Sueca IG 34

S2

I have searched the net whitout any trace. Inside the tube there is an spiral going from the socket and upp. I think it might be an indicator-tube of some kind?

Data wanted!!!

Hi Adalin

What is the size of your tube and what is the base configuration? Can you identify where the plate, heater, grid... are conected? Some times it can be a regular tube just with a different code.

Please, send more information and I will look on my manuals.

Regards.

Hi

The size of the tube is like an ordinary EL34
It´s Ocktalbase

I don´t think it´s an amplifiertube. I think it´s a "glimeye"

The only connections internaly is one pin whitch goes to the spiral
and one pin on each side of the spiral
a total of three pins

The question now is, How can I get it to light??

Hi

I was wondering if that should not be a kind of light bulb or gas-filled tube. Can you scan that and send me the image?

Hi Adalin

Despite the base I don't think it is a valve. My guess is that device is a kind of neon-gas light bulb. Have you tried to check if there is any resistence among its terminals? If I am right you will find an open circuit on all of them.

Try also to look for a voltage among terminals, just to make sure it is not a photo tube.

Sorry but I can't go further. Let's wait to see if some one recognize this tube.

P.S. I will send the picture to a friend to ask if he knows it.

Hi

you are right about it not beeing a valve.

It´s a neon-gas light bulb.

I got the answer on another forum and tried to plug it in.

It emmits a nice glow from the spiral. Orange and yellow and a little pink

It,s realy bright and nice.

But I still need data about it like maximum voltage and currentdraw and stuff.
Dont want to burn it just because I overvoltage it or something

Hi

I asked my friend about it and I am still waiting for the answer. I hope he has some data about it.

I would love to see that thing lighting.

Best regards

Hi Adalin

I wrote to Frank Philipse who agreed in putting your tube in his "data wanted" page. You may check that on

http://home.wxs.nl/~frank.philipse/frank/wanted.html

Do you have 58 of those!? Where did those came from?

Good luck with your project

Hi

Ok nice. Maybee I can get some data on them then.

I got them from a friend who got them from a friend so I dont know where they belong from the beginning...
